CodeBrowser: Add notice for large file

When a user tries to show a large file in CodeBrowser, show a notice to
tell that we can't show the file because of the size and a button to
show the file in raw. The button means "You can see the file in raw
instead".

If the user is a Site administrator, tell also that you can loose the
size limit.
CodeBrowser: Fix incorrect size limitation

The file whose size is equal to MAX_FILE_SIZE_CAN_BE_VIEWED should be
shown as well as smaller files.
